Overview
The VS421HD4K 4-port HDMI 4K switch lets you share a display or projector with four HDMI-enabled audio / video source devices. The switch features four independent inputs that each support 4K resolution and 7.1 surround sound audio.
The 4-port switch also features MHL support on HDMI input port 1, enabling video output video from MHL-enabled mobile devices such as Samsung Galaxy tablets and smartphones.
Astonishing Picture Quality with 4K Support
You’ll be amazed at how this video switch maintains Ultra HD picture quality. 4K is supported by the latest A/V devices and delivers four times the resolution of 1080p. Plus, because the switch is backward compatible with high-definition 1080p, you can rest assured any video source will look great in your digital signage application.
Solid Aluminum Housing Ensures Fixed Positioning
Constructed of solid aluminum, the HDMI switch is durable and heavy enough to prevent the unit from lifting or sliding around if the attached HDMI cables are bumped or shifted. Plus, its small footprint makes it easy to integrate the switch into any boardroom, classroom, home theater, or digital signage application.
Hassle-free Operation with Auto Switching & EDID
This switch ensures effortless operation with automatic switching that detects and selects a newly connected device. Automatic switching encourages on-the-fly collaboration among colleagues, by making it easy to share your projector between multiple source devices in a boardroom or classroom environment. The VS421HD4K also supports manual operation using the included IR remote control, or the built-in front panel toggle switch directly on the device.
The switch also saves time during setup with EDID emulation ensuring all of your native settings such as resolution and refresh rate are communicated between your display and video source devices. EDID emulation maximizes compatibility with your 4K display, ensuring a convenient plug-and-play installation.
The VS421HD4K is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Frequently Asked Questions
Before You Buy
Mobile High-Definition Link (MHL) allows a standard USB connector to carry digital video signals. To use the MHL output from a mobile device using a micro-USB connector, the MHL output must be converted by using an MHL adapter. MHL can only be adapted to HDMI.
Although many mobile devices use the micro-USB connector and the MHL adapters can plug into your mobile device, the mobile device still requires MHL support. MHL support is a hardware specification on your mobile device, and it cannot be resolved by applying updates of any type.
To determine if your mobile device supports MHL, research the manufacturer specifications for your mobile device. You can also search for your device on the following website: http://www.mhltech.org/devices.aspx.
To make sure that you select the correct adapter, you need to determine if you are using a 5-pin or 11-pin micro-USB. This information can usually be found with the MHL specification on your mobile device.
Different types of Samsung devices that use an 11-pin micro-USB require external power to perform the conversion. First-generation Samsung MHL 2.0 requires external power, whereas the second generation does not. A passive 11-pin cable can be used with second-generation Samsung mobile devices.
StarTech.com 5-pin and 11-pin adapters have a micro-USB receptacle to provide additional power to the mobile device. You can use a standard micro-USB cable with a USB charger to power the converter.
This device outputs HDMI video signals. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.
HDCP
When you consider whether to convert an HDMI video signal to another connection type, it is important to know if the media that is being converted from the HDMI video connection is protected by High-bandwidth Digital Content Protection (HDCP). If the media is protected by HDCP, you cannot convert to analog video connections because they do not support HDCP. You may experience this issue when you use devices like Blu-ray players, DVD players, and certain gaming consoles.
